What Makes ‘Once-A-Year Septic  Treatment’ So Different? No matter what septic system products call themselves – digesters, energizers, or conditioners – for the most part, they share one common trait – they must be used on a regular basis.  The reality is that all these products have a limited lifespan and limited ability to work in your septic system. Based on Nordevco’s proven BactiDomus  Biotechnology for treatment of municipal systems, community sewage lagoons and treatment plants, Once-A-Year Septic  allows you to use that same powerful technology to manage your septic system. Once-A-Year Septic  provides an easy to use, safe, non-toxic and non- caustic alternative to products that is effective and affordable. With less packaging, less work and a bottle that can be recycled to reduce waste, Once-A-Year Septic  translates into a more environmentally friendly solution to manage your septic system.

How Once-A-Year Septic  helps maintain your septic system: Using the same technology used to break down waste and improve operations in larger municipal lagoons, Once-A-Year Septic  will immediately begin to break down solids and sludge accumulated in your septic tank.  In addition, Once-A-Year Septic  will restore the proper biological balance to the system. This will have an immediate impact on the operation of the system, eliminating odours, and improving drainage and flows. 
As Once-A-Year Septic  continues to work in your septic tank, it will also begin to have a positive impact on your leach field.  As the solids and sludge in the septic tank break down, some of the Once-A-Year Septic  bacteria will be carried out to the leach field by organic particles that they have attached to where they will continue to break down organic material that is clogging the field.  As this organic material is broken down the leach field will begin to operate more efficiently and the signs of problems will begin to diminish and disappear: water ponding will stop and the raw sewage smells around the field will be eliminated. Once-A-Year Septic  will also break down the fats, oils and greases that end up in both the septic tank and leach field and that contribute to flow and drainage problems. It will also ensure that the scum layer that typically forms in the sedimentation chamber does not get too thick and inhibits the normal operation of the system.
